Muscle atrophy and fatty infiltration after an acute rotator cuff repair in a sheep model

Abstract

Muscle atrophy and fatty infiltration after an acute rotator cuff repair in a sheep model tration, and fibrosis related genes. Significantly increased adipocytes, muscle fatty infiltration, and collagen deposition was observed in rotator cuff muscles in the tendon repair group compared to the control group. Conclusions: rotator cuff muscle undergoes degradation changes including fatty infiltration and fibrosis even after the tendons
